GeForce 830M vs GeForce GT 430

Intro

Compare those specs to the GeForce GT 430, which features core speeds of 700 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 memory. It features 96 SPUs along with 16 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 830M		25 Watts
GeForce GT 430		60 Watts
	Difference: 35 Watts (140%)

Memory Bandwidth

The GeForce GT 430 should theoretically perform quite a bit faster than the GeForce 830M in general. (explain)

GeForce GT 430		28800 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 14400 (100%)

Texel Rate

The GeForce 830M is a lot (about 47%) more effective at anisotropic filtering than the GeForce GT 430. (explain)

GeForce 830M		16464 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 5264 (47%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 830M is superior to the GeForce GT 430, by far. (explain)

GeForce 830M		8232 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 5432 (194%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
